A few 390 questions...

This engine is in my truck and its a all stock 2 barrel engine. I am stepping up to a 4 barrel, aluminum intake, better cam and associated parts...I also have the Crane XRi drop in ignition for the distributor...

This is the Edelbrock 2105 intake...

The cam is a Edelbrock 2106...

The carb will be a 600 CFM Holley 80457...

My questions are these...

What valve springs should I run and with that cam...I as thinking maybe these?

These are the 1.76 rocker arms I want to run on the engine, will they work?

Always use the spring specified by the cam grinder. Edelbrock specs either of these springs for use with that cam.

I could be wrong, but I believe those needle bearing rockers have to run on a hardened shaft. Here's the whole kit....

That Edelbrock 2105 is what my buddy used to call a "weak suck operation". Step up to a high-rise Edelbrock RPM or Weiand Stealth. You should pick up 30-40 horsepower over the low-rise model.

The Weiand Stealth #7282 for the FE motor may have been discontinued, but should be available used on ebay or craigslist.

the Edelbrock RPM is only $45 more and is pretty much one of the top intakes for this engine.

After talking to Edelbrock, they OKed the cam and spring combo I am going to run and they told me to not run a bigger intake than what I have cause its "matched" to that cam and will work good with the carb also...I am planning to use ProComp's rocker arm/shaft combo with a new set of pushrods...I am using that intake and carb because I got both used for less than what my intake costs new...If I was buying new it might be different but I have only found 3 used aluminum FE intakes in the state of Florida and one of them I now have...And all 3 were the same...I went to the Turkey Run in Daytona last month and the only thing people had was CJ stuff and I'm not paying out the butt for a factory part...This is the updated list of stuff I have or am getting for the engine...

The standard Performer 2105 intake won't do much for you,actually an Edelbrock Streetmaster is probably the best all around choice for a 390 FE for your purpose, your cam selection is also a little too conservative for a 390 as is a 600 CFM carb which would be better served on a SBF Windsor Check out www.summitracing.com and run these part numbers in search: Howard 250031-12 and Holley 65-3310S this should produce a stout low end and mid-range,this Holley also has the Ford kickdown.
